I was under the impression that all cars running
on unleaded were burning 10% ethanol.

Nope. We have a choice of two grades of unleaded here
and E10 as well. The E10 is the only one that contains
ethanol and is a bit cheaper but doesnt give as good a mpg.

Or are you talking about the difference between diesel and petrol?

Nope.

I doubt there are any ethanol fuelled
cars outside of a race track or drag strip.

There are actually in some countrys like Brazil.

Engines designed to run fine on pure ethanol or unleaded petrol.

Can you explain though why there is a different smell to the exhaust on
Ethanol powered cars. Its like its sweet and almost sugary on the tip of
ones tongue, or is this just me and my peculiar sense organs!
